This image is from the Earth As Art 3 collection, and shows the Great Salt Desert of Iran, the Dasht-e Kavir, as seen from space.
It’s a nearly 30,000 square mile expanse of dusty plateaus and inhospitable salt marshes. But it’s also beautiful.
You can buy a large poster of this (or download an even huger graphic than this one) from the US Geological Survey.
